캄보디아와 탄자니아산 지르콘을 대상으로 메타믹상태와 색상변화에 대한 연구를 하였다. 이를 위해 U, Th 등의 방사성원소 검출을 위한 원소분석과 분광분석(UV-VIS 분광기, FTIR분광기)을 하였다. UV-VIS 분광분석 결과 청색과 무색에서는 고온형의 특징인 많은 흡수 피크들과 세기가 높게 나타났으며 우라늄이 검출된 녹색과 황색 시료에서는 흡수 피크들의 수가 현저히 적게 나타나 메타믹화가 진행되었음을 알 수 있었다. 열처리 후에는 반대의 결과가 나왔다. FTIR 분광 분석 결과 3100~3400 $cm^{-1}$ 영역에서 $[SiO_4]^{4-}$ 내부 진동의 3-포논 조합 모드 밴드들이 메타믹화된 녹색과 황색의 지르콘에서는 완만하며 없어진 밴드들도 있으나 열처리 후에는 다시 결정격자가 원상태로 회복되어 사라졌던 밴드들이 나타났다. 또한 지르콘에 우라늄이 함유되어 있는지를 알 수 있는 4800 $cm^{-1}$ 근처에서 $U^{4+}$의 피크가 녹색과 황색 시료에서 확인 되었다. 연구 결과 분광분석 과 열처리 실험으로 지르콘에 우라늄의 함유가 메타믹상태와 칼라의 변화에 미치는 영향을 확인할 수 있었다. Metamictization and color change in zircons from Cambodia and Tanzania were investigated. Elements analysis to detect radioactivity of elements such as U and Th, and spectroscopic analysis using UV-VIS and Fourier transform infrared spectroscopy were performed. According to the UV-VIS spectroscopic analysis, it was perceived that many and high intense absorption peaks appeared in blue and colorless zircons, while less and low intense absorption peaks appeared in uranium contained green and yellow zircons. It was found that those stones have made progress to the metamictization. After heat treatment, we could detect opposite results. As the results of FTIR spectroscopy analysis, in the metamict green and yellow zircon, it is showed that 3-phonon combination mode bands of $[SiO_4]^{4-}$ internal vibration in the region of 3100~3400 $cm^{-1}$ are broad and some of them disappear. However, the disappeared bands are observed again due to restored crystal lattice by the heat treatment. Also, $U^{4+}$ peaks that can detect the uranium content in zircon appears at near 4800 $cm^{-1}$ in the green and yellow samples. From this investigation, we could observe the metamictization effect and color change in uranium-bearing zircon by heat treatment using spectroscopic analysis.

MediaFrame: Parallel multimedia system architecture through HTTP redirection

김성기,한상영,Kim, Seong-Ki,Han, Sang-Yong Korea Information Processing Society 2007 정보처리학회논문지 A Vol.14 No.1

한 대의 비디오 서버가 확장성, 용량, 고장 감내(Fault-tolerance), 비용 효율성(Cost-efficiency)에서 한계들을 드러냄에 따라 해결책들이 나타났다. 그러나, 이러한 해결책들도 각각의 문제점들을 지닌다. 우리는 이러한 문제점들을 해결하고 다양한 비디오 서버들을 활용하기 위해, HTTP 레벨 리디렉션(Redirection)을 통하여 이질적인 퍼스널 컴퓨터(Personal Computer), 운영 체제(Operating System) 비디오 서버들로 내용에 따른 라우팅(Routing)을 지원하는 병렬 멀티미디어 시스템 구조를 디자인하였다. 또한 프로토타입을 개발하였으며 서로 다른 비디오서버 제품들을 프로토타입에 추가하였고 오버헤드를 측정하였다. As a single video server exposes its limitation in scalability, capability, fault-tolerance, and cost-efficiency, solutions of this limitation emerge. However, these solutions have their own problems that will be discussed in this paper. To solve these problems and exploit various video silvers, we designed a parallel multimedia system architecture that supported a content-aware routing to heterogeneous personal computer (PC), operating system (OS), video servers through a HTTP-level redirection. We also developed a prototype, added different video servers into the prototype, and measured its overheads.

김성기,노시균,이내호,양경무,Kim, Seong-Ki,Roh, Si-Gyun,Lee, Nae-Ho,Yang, Kyung-Moo 대한성형외과학회 2010 Archives of Plastic Surgery Vol.37 No.3

Purpose: High-pressure injection injury is caused by accidental injection of the high-pressure injection devices in industry. The initial benign appearance of the wound fools patients into delays in an adequate treatment. And it can result in disastrous outcomes such as necrosis and amputation. To avoid the poor prognosis, the injuries require a prompt surgical intervention. The purpose of this article is to recognize the poor outcome of the highpressure injection injury and to introduce an adequate treatment in need. Methods: We have 4 cases of the high-pressure injection injuries in the hand from April, 2005 to March, 2009. Average age is 39 years (30 - 49 years old), 2 cases are the palm of dominant hand, 1 case is the thumb of dominant hand, and 1 case is the palm of non-dominant hand, respectively. We followed up these patients for 20 months on average. In 3 cases, the immediate, aggressive surgical intervention was carried out, but the other one was delayed in early adequate treatment. The wounds were covered by local advancement flap, anterolateral thigh free flap, conservative treatment with antibiotics and dressing. Results: No pathogens after culture were found nor any findings of fracture in imaging study. Conservative treatment, local advancement flap and anterolateral thigh free flap for the open wound resulted in a desirable aesthetic outcome. In a long-term follow up, functional capability of the patient was also satisfactory. Conclusion: Upon initial evaluation, most high-pressure injection injuries present as innocuous wounds with very few symptoms and result in delaying the proper management. And the majority of high-pressure injection injuries will produce significant morbidity to the hand, amputation. And the initial aggressive surgical debridement was needed to prevent the poor outcome. The key to success in treating high-pressure injection injuries of the hand is the prompt aggressive surgical intervention.

김성기,노시균,이내호,양경무,Kim, Seong-Ki,Roh, Si-Gyun,Lee, Nae-Ho,Yang, Kyung-Moo 대한미세수술학회 2013 Archives of reconstructive microsurgery Vol.22 No.1

Purpose: Reconstruction of scalp and calvarial defects should provide both aesthetic and functional aspects. The inelastic nature of the scalp and previous surgery or radiation preclude the use of primary closure or a local flap. With development of microsurgical technique, a free tissue transfer is a good option. We use the latissimus dorsi myocutaneous free flap for reconstruction. Materials and Methods: A review of all latissimus dorsi free flap reconstructions performed in nine patients from 2009 to 2012 was conducted. There were six males and three females, ranging in age from seven to 69 years, and nine different regions, including five temporal regions, two occipital regions, and two frontoparietal regions. The flaps ranged in size from $9.0{\times}10.0cm$ to $14.0{\times}15.0cm$. Recipient vessels available for microanastomosis were most often the superficial temporal vessels and two patients had anastomoses to the external carotid artery and internal jugular vein. Results: All flaps survived postoperatively. With a median follow-up period of 14 months, no major complications were noted. However, two patients developed minor wound dehiscence, and a hematoma was observed in one patient. Conclusion: We performed the latissimus dorsi myocutaneous free flap reconstruction, which is one of the most popular reconstructive methods. The latissimus dorsi myocutaneous free flap reconstruction has been proven successful in our patients with satisfactory results. During the long term follow-up period, even though depressions were observed on the defect area in some patients, they were treated successfully with cranioplasty. Therefore, we recommend the latissimus dorsi myocutaneous free flap for reconstruction of scalp and calvarial defects.

낙동강 수계의 20개 저수지 및 습지에서 환경요인에 대한 동물플랑크톤 군집의 영향을 평가하기 위해 계절별 조사를 수행하였으며 다양한 환경 요인에 대한 동물플랑크톤의 영향을 효과적으로 분석하기 위해 Self-Organizing Map(SOM) 분석을 이용하였다. 총 109종의 동물플랑크톤 종이 동정되었으며, 동물플랑크톤의 밀도와 종수는 계절에 따라 상이한 분포를 나타냈다. 특히, 가을은 다른 계절보다 동물플랑크톤의 높은 종수와 밀도를 기록하였다(98종, 603 ind. /L). 윤충류는 다른 환경요소보다 수온과 밀접하게 연관되었으며, 이는 계절에 따른 영향을 크게 받는 것으로 보인다. 지각류 와 요각류는 전기전도도, Chl. a, 영양염류(TN, TP) 대해서 영향 받았으며, 이는 오염원 및 먹이원에 영향을 크게 받는 것으로 보인다. 그러나, 용존산소가 높은 정수역에서는 대부분 동물플랑크톤이 낮은 밀도를 보였다. 저수지 및 습지에서 출현하는 동물플랑크톤 군집은 수온이나 영양염류 등의 환경요인에 대해 주로 영향 받는 것으로 평가되었다. 결론적으로 저수지와 습지와 같은 정수역에서 출현하는 동물플랑크톤 군집의 조성 및 밀도는 환경요인과 밀접하게 연관되는 것으로 나타났으며, 환경요인의 변화는 동물플랑크톤의 계절성을 결정하는 중요한 요인인 것으로 평가되었다. In order to estimate the influence of environmental factors on zooplankton communities in lentic freshwater ecosystems, 20 reservoirs and wetlands were monitored by season in 2013. A total of 109 species of zooplankton were identified during the study period. Zooplankton assemblage showed a different distribution in its density and diversity in accordance with the seasons. In particular, the density of zooplankton (98 species and 603ind. L-1) was the most in autumn when compared to the other seasons. In order to effectively analyze zooplankton distribution that are affected by various environmental factors, a Self-Organizing Map (SOM) was used, which extracts information through competitive and adaptive properties. A total of 11 variables (8 environment factors and 3 groups of zooplankton) were patterned on to the SOM. Based on a U-matrix, four clusters were identified from the model. Among zooplankton communities, rotifer displayed a positive relationship with water temperature, and cladocerans and copepod were positively related to conductivity, chlorophyll a, and nutrient factor (i. e. TN and TP). In contrast, high dissolved oxygen appeared to have a negative effect on zooplankton distribution. Consequently, the SOM results depicted a clear pattern of zooplankton density clusters partitioned by environmental factors, which play a key role in determining the seasonal distribution of zooplankton groups in lentic freshwater ecosystem.
